使用正则表达式删除首字母缩略词，基于括号后的大写字符

Question

如何删除以下内容：

首字母缩写词以左括号开头，后跟大写或编号：例如'(ABC' 或 '(ABC)' 或 '(ABC-2A)' 或 '(ABC-1)'。

但是不是括号之间以大写字母开头后跟小写字母的单词，例如'(Bobby)' 或 '(Bob went to the beach..)' --> 这是我苦苦挣扎的部分。


text = ['(ABC went to the beach', 'The girl (ABC-2A) is walking', 'The dog (Bobby) is being walked', 'They are there (ABC)' ]
for string in text:
  cleaned_acronyms = re.sub(r'\([A-Z]*\)?', '', string)
  print(cleaned_acronyms)

#current output:
>> 'went to the beach' #Correct
>>'The girl -2A) is walking' #Not correct
>>'The dog obby) is being walked' #Not correct
>>'They are there' #Correct


#desired & correct output:
>> 'went to the beach'
>>'The girl is walking'
>>'The dog (Bobby) is being walked' #(Bobby) is NOT an acronym (uppercase+lowercase)
>>'They are there'

Answer 1

使用模式\([A-Z0-9\-]+\)

例如：

import re

text = ['ABC went to the beach', 'The girl (ABC-2A) is walking', 'The dog (Bobby) is being walked', 'They are there (ABC)' ]
ptrn = re.compile(r"\([A-Z0-9\-]+\)")
for i in text:
    print(ptrn.sub("", i))

输出：

ABC went to the beach
The girl  is walking
The dog (Bobby) is being walked
They are there

Answer 2

在以下上下文中使用 \([A-Z\-0-9]{2,}\)?：

import re

text = ['(ABC went to the beach', 'The girl (ABC-2A) is walking', 'The dog (Bobby) is being walked', 'They are there (ABC)' ]
for string in text:
  cleaned_acronyms = re.sub(r'\([A-Z\-0-9]{2,}\)?', '', string)
  print(cleaned_acronyms)

我得到这些结果：

' went to the beach'
'The girl  is walking'
'The dog (Bobby) is being walked'
'They are there '

Answer 3

尝试使用负前瞻：

\((?![A-Z][a-z])[A-Z\d-]+\)?\s*

在线查看demo

\( - 文字开头的括号。
(?![A-Z][a-z]) - 否定先行断言位置后跟大写后跟小写。
[A-Z\d-]+ - 匹配 1+ 个大写字母字符、数字或连字符。
\)? - 一个可选的文字结束括号。
\s* - 0+ 个空白字符。

一些示例 Python 脚本：

import re
text = ['(ABC went to the beach', 'The girl (ABC-2A) is walking', 'The dog (Bobby) is being walked', 'They are there (ABC)' ]
for string in text:
  cleaned_acronyms = re.sub(r'\((?![A-Z][a-z])[A-Z\d-]+\)?\s*', '', string)
  print(cleaned_acronyms)

打印：

went to the beach
The girl is walking
The dog (Bobby) is being walked
They are there
